"Liam [Hemsworth]'s a great guy," Billy Ray told ET Canada in an interview on Wednesday. "I like Liam a lot."

The singer and the Aussie actor got engaged on May 31 after three years of dating, and Miley, 19, told PEOPLE at the time, "I'm so happy to be engaged and look forward to a life of happiness with Liam."

Happiness, as it turns out, runs in the family, says Billy Ray, who took great pleasure in his daughter's news.
